All math problems with a solution will have some sort of formula to solve it , but I can assure you they can not all be solved from common sense only.

Multiply that with 20 teams and divide the answer by two , because there are two teams in each match.https://community.betfair.com/general_betting/go/thread/view/94082/23488154/maths-help?post_id=419581270#419581270Why do you need a formula when commom sense will do it for you : They all will play 38 matches.
